Jul 10, 2024 · photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

5 days ago · Overview. Photosynthesis changes sunlight into chemical energy, splits water to liberate O 2, and fixes CO 2 into sugar. Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light.
Jul 10, 2024 · When photosynthesis was stopped after two seconds, the principal radioactive product was PGA, which therefore was identified as the first stable compound formed during carbon dioxide fixation in green plants. PGA is a three-carbon compound, and the mode of photosynthesis is thus referred to as C 3.
Jul 1, 2024 · The process occurs in almost all algae, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella. Photosynthesis comprises both light reactions and dark reactions (or Calvin cycle).
Jul 10, 2024 · Photosynthesis provides the foundation for life on Earth by making our atmosphere oxygen rich; it also sequesters carbon pollution from human activity and forms the basis of the food chain.
1 day ago · The origin of leaves was almost certainly triggered by falling concentrations of atmospheric CO 2 during the Devonian period, increasing the efficiency with which carbon dioxide could be captured for photosynthesis. Leaves evolved more than once.

Jun 25, 2024 · The glucose produced in photosynthesis may be: Used for respiration (both aerobic and anaerobic) Converted into insoluble starch for storage in the stems, leaves and roots. Used to produce fat or oil for storage (especially in seeds) Used to produce cellulose, which strengthens the cell wall.
